Wow.
First off, not a fan of the snare sound, but thats just personal opinion, sounds quality is good.
Really like the ambient guits, on that note during the climaxes, there seems to be almost too much going on, maybe you could create some space with panning, or maybe dynamic changes, allowing some of the tracks be underlying instead of all fighting for their spot in the front.
Tone wise things sound great, am interested in hearing it with vox.
